Before you start developing applications on MapR’s Converged Data Platform, consider how you will get the data onto the
platform, the format it will be stored in, the type of processing or modeling that is required, and how the data will
be accessed.

A MapR Expansion Pack (MEP) provides a set of ecosystem components that work together on one or more MapR cluster versions.
Only one version of each ecosystem component is available in each MEP. For example, only one version of Hive and one version
of Spark is supported in a MEP.

Starting with MapR Expansion Pack (MEP) 6.0.0, MapR Object Store with S3-Compatible API (MapR Object Store) is included in MEP repositories. To fully benefit from the MapR Object Store, it is important to understand what the
MapR Object Store is and how it works, how to authenticate it and perform bucket operations.

MapR supports public APIs for MapR Filesystem, MapR Database, and MapR Event Store For Apache Kafka. These APIs are available for application development purposes.

Hive and MapR Database Integration

You can create MapR Database binary tables from Hive that can be accessed by both Hive and
MapR Database. You can run Hive queries on MapR Database binary tables, convert existing MapR Database binary
tables into Hive-MapR Database tables, and run Hive queries on those tables as well.
